Initiating the ketogenic diet in infants with treatment refractory epilepsy while maintaining a breast milk diet.

PURPOSE: The ketogenic diet has been found to be safe and effective in the treatment of drug resistant epilepsy in childhood. The age range of children undergoing this treatment has steadily been going down. There is strong evidence that it is a safe alternative in infants with drug resistant seizures. The American Academy of Pediatrics strongly supports continuing a breast milk diet until infants are at least six months of age. The purpose of this study is to evaluate the safety and efficacy of the ketogenic diet in infants while maintaining a breast milk diet. METHOD: This is a cohort study of 9 infants between the ages of 1 and 13 months with drug resistant epilepsy treated with the ketogenic diet while maintained on breast milk. The data from the first two patients was gathered retrospectively while the other seven were studied prospectively. RESULTS: We show that all nine infants achieved and maintained ketosis effectively. While one infant had no change in seizure frequency, three were seizure free at the first follow-up visit and four had a burden of seizure reduction greater than 50%. The diet was overall well tolerated, although one child required a hospital stay for dehydration and metabolic acidosis. CONCLUSION: The ketogenic diet can be safely and effectively initiated in infants while continuing human breast milk feedings.

A refresher on Tourette syndrome.

Tourette Syndrome (TS) is recognized as a more common neurodevelopmental disorder than once thought. In this article we present an update on TS including the DSM-5 revised criteria, new findings in the genetics of TS, treatment advances such as new medications for tics and the use of new tools including Cognitive Behavioral Intervention for Tics (CBIT). We also explore supportive services for the ongoing care of patients using nursing education and family therapy.

Pretreatment EEG in childhood absence epilepsy: associations with attention and treatment outcome.

OBJECTIVE: In children with newly diagnosed childhood absence epilepsy (CAE), determine pretreatment EEG features and their associations with baseline neuropsychological function and short-term treatment outcome. METHODS: In a multicenter, randomized clinical trial, patients with CAE underwent a pretreatment, 1-hour video-EEG and neuropsychological testing with freedom-from-failure and seizure-freedom (SF) outcome assessed at the 16- to 20-week visit. RESULTS: Detailed evaluation of the pretreatment EEG was possible for 99.8% of participants (445/446). Median time to first seizure was 6.0 minutes (range 0-59 minutes), median number of seizures was 5 (range 1-60), and median seizure duration was 10.8 seconds (range 3.3-77.6 seconds). Median duration of shortest seizure per EEG was 7.5 seconds (range 3.0-77.6 seconds). Seizure frequency was not associated with baseline measures of attention, executive function, or treatment outcome. Presence of a seizure lasting ≥20 seconds was noted in 29% of subjects (129/440); these children had higher median omissions T score on the Conners Continuous Performance Test (56.3 vs 51.6, p = 0.01). Patients with a shortest seizure of longer duration were more likely to demonstrate treatment success by both freedom-from-failure (p = 0.02) and SF (p = 0.005) criteria, even after controlling for age, treatment group, and number of seizures, with good predictive value (area under the curve 78% for SF). CONCLUSIONS: CAE is reliably and quickly confirmed by EEG. Occurrence of a seizure ≥20 seconds, but not overall seizure frequency, was associated with differential baseline measures of attention. Patients whose shortest pretreatment EEG seizure was longer in duration were more likely to achieve SF, regardless of treatment.
